Application filed September To @ZZ wiwm 2725 conceive,

Be it known that I, Sant-ELA. Minnie encens, a citizen ol the United States, and resident ot Mec-on, in the county of Bihh" and State of Georgia, have invented new and useful improvements in Cerbureters, of which the following is a'speciiication,

My invention relates to cerhureters, and has particular reference to that class of oarhureters used in connection with internal combustion engines.

An .important object of the invention is to provide in a device of the above mentioned character a. means which will make possible the using' of heavy hydro-carbon liquid as a fuel te produce a. resultequai in eect to that produced in the use oi' the lighter hydro-carbon liquids non" commonly empoyed as a. fuel.

A further ohject of the linvention is tov provide in a device of the above mentioned character ay Ineens whereby the hydro-cali)onv liquid may he uniformly heated prior to the exposure ofthe same to en air current in its course of travel through the Carlini-eter and into the explosion ehamher of en internal combustion engine.

A further object of tie invention is to, provide in a. device of the above mentioned character a4 means for heating the air @un rent prior to the contiactingI of the saine with the hydro-carhon liquid end e means whereby the heated air, eter having' heconie saturated with the volatilieed liquid, may he kept et a uniform temperature in its course. of travel into the combustion chamber of an internal combustion engine.

further object of the invention Vis to provide in a device of the above mentioned character a means whereby the air current and volatilized liquid may he uniformly mixed thereby forming a. highly homogeneous mixture, rendering the 'explosive charge, when exploded Within the eylinder of an internal comhustion engine, more eifective than would otherwise he possible.

Other objectsand advantages of the invention will he apparent during the course of the following description.

inthe accompanying drawings forming' a part of this specification and in which like numerals are employed to designate like parts through the saine,

In the drawings, wherein for the purm pose of illustration is shown a preferred yembodiment et my invention, the numeral 5 designates an exhaust manifold having openings or ports indicated by the numeral ii Which are adapted to register with the intake ports of an internal Combustion engine not shown). Within the exhaust manifold 5 there is disposed an intake manifold 7 adapted to open into the ports or Openings 8 which are adapted to register-With the intake openings oe ports `eligen internal combustioi'i engine. This intake manifold may he east integral with 'the ei:- haust manifold or formed in any other defeired manner.

One end of the exhaust lani- ,fold is provided with a pipe l() 'and servos to connect the interior of the exhaust menifold with a jacket provided 'hy a @einem reter indicated as a Whole by the numeral ll. The earloureter il comprises a howl l2 'which is provided with -vail l'spaced therefrom, forming a jacket le between the howl l2 and Lhe Wall 13.

to sever eonnnunication between the carbureterll and the auxiliary earbureter 48, one of which eerbureters is thereby brought into communication with the interior of the intake niaiiifold 7 as Shown in Fig. 2. This valve is adapted to be operated by ineens of e. lever Connected thereto and shown in Fig. l.

pipe .3l is connected to the Well 18, which pipe is in turn connected to the ex hirnst manifold 5 es clearly shown in Fig.. l :ind 2. pipe 52 is seeiired to the pipe 5l and Spirced en appreciable distance therefrom on its inner side to allow the passage of air between the pipe 5l and the pipe 52, the pipe 52 being in turn connected to the auxiliary cerbureter 48'.

The exhaust manifold 5 is provided on its ripper side with zi dome 53 heif'ing disposed 'thereupon e, Cep 54 which serves :is a closure for the seine. VJithin the dome there is provided o governor indicated :is :L AWhole by the numero-l This governor is connected to the rotary veli/e 46 by ine-zins of a stein 56 housed Within e. easing 57 Carried Within the exhaust manifold 5. The governor is 'dapted' to be operated by n flexible shaft 58 connected by any suitable ineens to :i rotating` member of en internal combustion engine 'for the purpose of operatingthe seme.

To the erthere iseonneeted a link 62 which in turn is connected to an erin G3 similar to that indicated by the numerni 32. the erin 63 beingr operably connected to e valvee not shown,` which Valve is arrange-d `Nithin the carbureter 48 and identical with the valveindion-ted bythe numeral 34e. it is obvious therefore that when the voire 34e is moved the valve to Whieh the iever GB is ooenevted is iiliewise moved.

The operation of the device is :is follows: il' hen it is desired to start en internal Coin- 'bnetion engine with which my device is need, the rotary Valve moved to the position shown in Fig. 2, wi ereiipon ,que from Vthe carburetor 8, einpioyine; li ght hydroirrbon ne n inni, j neierebly gesolene, which is Sup plied thereto through the pipe (il, is eiiowed to enter the intake. ineniiiold and pees into ihe eoinbnetion eheinber of in interneiweom hnsi'ion engine. .ff-r portion or the hot 'limiet enses., esvziping from the internal eoniN imstion engine through lthe ports G into the manifold is transmitted to the Coil or" pipe 535, carryingv ii heavy liquid hydrocarbon fuel, preferably kerosene, by ineens oi the 10 and 5l. `When the kerosene hns heeome sufficiently heated to cause it to reed ily 'voletilize the rotary valve is moved to :i position indicated by the dotted iine in Fie'. 2, whereby communication between the intake ninniifoldlnnd enrbmeter 48de and :it the Some time roinmnnieetion is eetehliehed between the enrbureter l1 and the manif-old 7. The valve is then -pipe Y10. is transmitted downwardly into the depending tubular member L6 and into con-.

tact with the fuel contained'within the cup 26'. The air after having vbecome saturated :with particles of the fuel travels upwardly through the nipple 20, into the outlet 19,

' and into the intake manifold 7. This mixture is agitated in its course of travel through the outlet 19 by means "of a mixer 19' revolubly mounted therein for the pur-V pose of forming ture. The travel of mixture through the outlet 19 is governed by means of the valve 34 a more homogeneous mix which is opened or closed simultaneously I.

bowl provided with a jacket, `a coil of fuel with the opening or closing oi'- the valve 25. The rotary valve 46 serves to govern the flow of mixture into the intake manifold 7., As theengine increases in speed the valve, under the .influence of the governor 57,

gradually closes lthus allowing less fuel to enter the combustion chambers of the engine,

f thereby decreasing the speed oithe same.

mixture to enter the combustion chamber of As the speed of the engine decreases, the valvee gradually opens, allowing more the engine whereupon the speed ofthe same will be accelerated. g f

'lt is to be understood that the form of my invention herewith Shown and described is to be taken as alprefcrred example or" the same, and that various changes in the shape,

size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
